Description
Technical field
The present invention relates to the communications field, relate in particular to the offline charging technology.
Background technology
SIP (Session Initiation Protocol, Session initiation Protocol) is a kind of VoIP standard of internet engineering task group (IETF) issue.(SIP has the unique user's addressing and the function of location as call signaling protocol for Quality ofService, the QoS) requirement of aspect, and it has obtained important application in internet (Internet) to telephone signaling and service quality along with the user.SIP can control the foundation and the termination of the Multimedia session of a plurality of participants' participation, and can dynamically adjust and revise session attribute, as the code/decode format of session bandwidth requirement, transmission medium type (voice, video, data etc.), medium, to support of multicast and clean culture or the like.Therefore SIP helps combining with the internet exploitation and multiple value-added service is provided.
IMS (IP Multimedia Subsystem, IM CN subsystem) is the subsystem that 3GPP superposes on packet network, it introduces the professional control protocol of Session Initiation Protocol as the bearer path of control signaling and media delivery, and utilize simple, easy expansion, the media combination characteristics easily of SIP, by business control is separated with carrying control, provide abundant multimedia service.The framework of IMS system as shown in Figure 1, comprise functions such as control user registration, session CSCF (conference call controlled function entity), IBCF (Interconnection Border Control Function entity), PGCF (packet gateway controlled function entity), manage the HSS (home subscriber server) of user contracting data concentratedly, the AS major function entities such as (Application Server, application servers) of miscellaneous service logic control function is provided.
When the user uses Session Initiation Protocol when the IMS network is registered, the IMS network authenticates and sets up the input field escape way to user's privately owned sign.After the user registration success, will set up the relation between IP multimedia pUblic identity and this user's current location at the S-CSCF of home domain, and described S-CSCF takes off user's IMS subscription data, i.e. IFC information simultaneously from HSS.
The user's who downloads at described S-CSCF IMS subscription data promptly in the IFC information, comprise one or more business descriptions, wherein comprise public identifier, core net service authorization, inceptive filtering rule set in each business description, share inceptive filtering rule set information.Wherein said initial filter criteria is one group of user's a service parameter.An inceptive filtering rule set comprises the tabulation that a plurality of initial filter criteria are formed.An initial filter criteria comprises following information:
The address information of the application server that 1, is triggered (AS).
2, Service Point Trigger.
3, with the filtering rule corresponding priorities.
In order to send the AS of relevant service request to correspondence, an initial filter criteria will trigger one or more Service Point Trigger.In order to make S-CSCF handle different initial filter criteria in the correct order, each initial filter criteria all is assigned a priority.
4, default treatment mode.
If S-CSCF can not relate to corresponding AS according to described initial filter criteria, this moment, S-CSCF used a default treatment mode to handle, and this default treatment mode is:
Trigger item if in the initial filter criteria tabulation, mated a low priority, then continue check.Or, abandon and tabulate in the verification of low priority coupling, and discharge described business.
5, optional business service information.
After described S-CSCF receives request message,, the trigger message in described request message and the trigger point is mated according to initial filter criteria priority order from high to low.If the match is successful, then described S-CSCF sends the AS of association request message to the matching initial filtering rule by ISC interface.
If described request message is login request message, then described S-CSCF sends third-party registration message for the AS of each matching initial filtering rule.
If described request message is other request, then described S-CSCF adds original dialogue sign and routing iinformation in the association request message that the AS that gives each matching initial filtering rule sends.AS according to described routing iinformation, returns to S-CSCF with request message after handling service logic.Described S-CSCF will proceed the triggering rule coupling of low priority, until all the triggering rule inspections in the business description are finished.
Described S-CSCF is as follows to the concrete processing procedure of existing session:
In the step 1, described S-CSCF checks whether the original dialogue sign that S-CSCF was placed in the Route header field in the past is present in the highest item that the Route header field is asked in arrival.If there is no, it represents that this request message is to visit described S-CSCF, the request message that promptly newly receives for the first time; If have the original dialogue sign in the Route header field in the request the highest, its expression described request message is to exist with existing dialogue to get in touch, promptly described request message be from AS send for previous transmission request responding.
Step 2 checks that whether the SPT trigger point in the described service request is complementary with the highest SPT trigger point of initial filter criteria medium priority, if do not match, then jumps to step 5; If be complementary, then execution in step 3.
Step 3, at first be that described business request information is added special identifier and routing iinformation, and in the P-Charging-Vector header field, carry the ICID parameter, in the Route header field after the highest the URI, insertion will be got in touch AS URI, transmit described business request information with the ISC interface between AS to corresponding AS by described S-CSCF then.
Because described S-CSCF is that service request from user has been added the original dialogue sign, even therefore the attribute of the business that the user asked (for example changes, because AS has carried out third-party session control), described S-CSCF also can discern the business request information that receives according to described original dialogue sign.
Step 4 after described AS receives the business request information that described S-CSCF sends, is carried out service logic, and after finishing service logic and handling, according to the routing iinformation transmission request relevant with described service request of carrying in the described business request information.
In step 4, provide professional alternately by ISC interface between described S-CSCF and described AS, its framework as shown in Figure 2, comprise described S-CSCF and described AS, wherein said AS comprises SIPAS (sip application server), IM SSF (Service Switching Function, Service Switching Function) and OSA-SCS (service capability server that open service inserts) several types.Described SIPAS is used to provide some service, and it can be based on SIP session of service impact.Described IMSSF is the AS of a specific type, and it is the characteristic (for example: trigger the finite state machine of DP point, CAMEL service exchange etc.) that is used for being responsible for the CAMEL net, and it provides a CAP interface.Described OSA-SCS is used for providing an interface to OSA AS, and it is inserted the IM subsystem for third party's safety a standard mode is provided.
Above-mentioned various types of AS carries out service logic after receiving the SIP request of S-CSCF transmission, and in the process of carrying out service logic, AS can adopt following several model to come treatment S IP request.
1, AS is as termination UA (User Agent, user agent)
Under this operation model, after AS receives a request from S-CSCF, carry out the termination UA or the Redirect Server role of definition among the RFC 3261.
2, AS is as PROXY (acting server)
Under this operation model, after AS receives a request from S-CSCF, carry out the PROXY role who defines among the IETF RFC3261, request is sent it back S-CSCF, S-CSCF acts on behalf of this message and gives the destination then.In the agent operation process, AS can be according to the rule of the PROXY that describes among the IETF RFC 3261, the header field content in increase, deletion and the modification SIP request.
3, AS is as B2BUA (Back to Back User Agent, back-to-back user agent)
AS is during as the route B2BUA, after AS receives a request from S-CSCF, this request that terminates, and generate a new SIP request of a different SIP dialog based on this request that receives, and sending to S-CSCF, S-CSCF arrives the destination with this request broker then.Under this model, AS carries out the role of the B2BUA of a plurality of SIP dialog of describing among the IETF RFC 3261.
After if the request relevant with service request that described AS sends arrives described S-CSCF, continue execution in step 5.
Step 5, described S-CSCF proceeds the initial filter criteria coupling of low priority, until all the initial filter criteria inspections in user's the subscription data are finished.
In the process of above-mentioned triggering business, for a designated user and S-CSCF thereof, special setting according to initial filter criteria, not only support different business to arrive the triggering of different AS, can realize simultaneously of the repeatedly triggering of same business, thereby realize associative combination same user's value-added service logic to a plurality of AS.
Prior art related to the present invention is the method that the S-CSCF that provides in present 3GPP TS24.229 and TS 32.260 standards charges to managing business, its implementing procedure as shown in Figure 3:
Described S-CSCF is under the situation that professional control is arranged, if the highest item does not have the original dialogue sign in the Route header field in the INVITE that the receives request, then preserve ICID (the IM CN subsystem Charging Identifier that from the P-Charging-Vector header field, receives, the IMS charging identifier) parameter is used in order to subsequent charging.Described then S-CSCF sends to destination after carrying out Service Control (service control) according to the information of carrying in the described INVITE.
Step 2, described S-CSCF receives the final response that destination is replied, promptly receive the response message of the 200OK of destination loopback, and carry out ServiceControl according to the information of carrying in the described response message, send described P-CSCF then to, and send described user UE to by described P-CSCF.
Step 3 after described S-CSCF receives the final response that destination replys, also sends Accounting-Request (request of chargeing) message and gives local CDF network element, starts user's session charging.Execution in step 4 then;
Carrying in the described Accounting-Request message with Client-initiated and calling out the ICID parameter that is associated.
Step 4 after described local CDF network element receives Accounting-Request message, is chargeed according to the ICID parameter of carrying in the message, and is replied described S-CSCF.
Step 5 after described P-CSCF receives final response, sends Accounting-Request message to visit CDF network element, starts user's session charging.Execution in step 6 then.
Carrying equally in the described Accounting-Request message with Client-initiated and calling out the ICID parameter that is associated.
Step 6 after described visit CDF network element receives Accounting-Request message, is chargeed according to the ICID parameter of carrying in the message, and is replied described P-CSCF.
By prior art as can be seen, prior art is by first IMS entity of process user session or conversational service, be that S-CSCF is in the trigger process of customer service control, only when receiving service request from user message, produce the ICID parameter relevant with described user's business, the business of the user being carried out according to the described ICID parameter statistics of chargeing is no longer followed the tracks of the variation of the ICID parameter of ISC interface afterwards.If yet when AS changes service media as the B2BUA role, because the ICID parameter is the data of session or dialogue (Session) level, so the ICID parameter also will change, at this moment S-CSCF can not carry out offline charging to the business after being modified.

Embodiment
From the 3GPP standard, there are two kinds of understandings in " Session " in charging, and a kind of is the notion of the dialogue (Dialog) among the RFC3261, and another is the notion of the session (Session) among the RFC3261.
Among the present invention, after network entity receives business request information, and when confirming that business request information to be sent changes, use new charging identifier to identify the charge information of the customer service request of corresponding described variation; When described network entity receives the final response of respective user service request, start offline charging to described new charging identifier corresponding service request according to described new charging identifier.Between the initiator that wherein said service request is meant in service request and the final receiver of described service request, by related one or more dialogue of this request, perhaps, one or more session, perhaps, one or more standalone transaction.
First embodiment provided by the invention is the dialogue notion at wherein, its main thought is: after the charging identifier in the business request information that the S-CSCF NE Discovery receives changes, store described new charging identifier, and after the final response that receives user's request, utilize described new charging identifier to start corresponding professional offline charging.
Its specific implementation process comprises the steps: as shown in Figure 4
When confirming that the original dialogue sign does not exist, represent that then described relevant business request information is to visit described S-CSCF network element for the first time, that is to say, the business request information that described S-CSCF receives is sent from calling subscriber or Calling Side network element, only exist original charging identifier this moment, so execution in step 2.
Step 2, described S-CSCF network element is preserved the original charging identifier in the described business request information that receives, and is transmitted to the AS network element that matches then.
Described S-CSCF network element is preserved the original charging identifier in the described business request information that receives, take out the initial filter criteria in the user contracting data then, and mate according to the priority sequencing from high to low of described initial filter criteria, when matching corresponding filtering rule, then business request information is sent to the AS network element of the initial filter criteria correspondence that matches by ISC interface, and original dialogue sign is added in the message of transmission (in the Route header field in the session request message), then described message is sent to the AS network element.
When there being original dialogue when sign, the response of business request information that described S-CSCF network element the receives service request that to be the AS network element be forwarded to the S-CSCF network element is described.This moment, described S-CSCF network element checked whether the charging identifier in the described business request information changes, and when confirming that described charging identifier changes, then store the new charging identifier in the business request information that receives, and after the final response of the request of receiving, utilize described new charging identifier to start to corresponding professional offline charging.Specific implementation process is as follows:
Step 3, described S-CSCF network element checks whether the charging identifier in the described business request information changes, and whether the charging identifier in the described business request information that promptly described S-CSCF network element judgement receives is identical with the charging identifier in the business request information that before mail to this AS:
If charging identifier is identical, illustrate that then charging identifier does not change, so execution in step 4, described S-CSCF continuation in the business request information that sends are used the corresponding professional charge information of preserving last time of charging identifier sign, and utilize the offline charging of its startup to customer service.
If the charging identifier difference illustrates that then change has taken place charging identifier, so execution in step 5, described S-CSCF network element is stored described new charging identifier, and uses the described new corresponding professional charge information of charging identifier sign.And receive the final response of request when described S-CSCF entity after, utilize described new charging identifier to start the offline charging of the business that described user is carried out.
In addition, in step 5, when change has taken place in charging identifier, described S-CSCF network element can also produce the association identification of related described original charging identifier and new charging identifier, and after the final response of the request of receiving, utilize described association identification and described new charging identifier to start the offline charging of the business that described user is carried out.Specific implementation process is as follows:
After described S-CSCF NE Discovery charging identifier changes, at first store described new charging identifier, produce an association identification then and remove related described new charging identifier, and other original charging identifier.Receive the final response of request when described S-CSCF entity after, utilize described association identification and described new charging identifier to start the offline charging of the business that described user is carried out.
In addition, can pass through other network element if arrange association identification in advance, S-CSCF network element as described in passing to as the AS network element.In step 5, when change had taken place charging identifier, described S-CSCF network element was carried out following process:
After described S-CSCF NE Discovery charging identifier changes, at first store described new charging identifier, and check the association identification that whether has related described original charging identifier and new charging identifier in the described session request message, when confirming to have association identification, then described S-CSCF network element also will be preserved described association identification.If there is no, then described S-CSCF network element need produce an association identification, is used for charging identifier after related described original charging identifier and the one or more change.
Receive the final response of request when described S-CSCF entity after, utilize described association identification and described new charging identifier to start the offline charging of the business that described user is carried out.
Second embodiment provided by the invention also is the dialogue notion at wherein, its main thought is: after network entity AS receives business request information, before continuing to transmit the corresponding service request, described network element entity is handled described business request information according to its function that has (have the Proxy function or have the B2BUA function).Specific implementation process is as follows:
After network entity AS receives business request information, before continuing to transmit the corresponding service request,, then in the business request information of sending, continue to use original charging identifier if described network element has the Proxy function.
If described network element has back-to-back user agent B2BUA function, then the service request after changing is produced new charging identifier.Described network entity AS can utilize described new charging identifier to start corresponding professional offline charging after the final response of the request of receiving.Be implemented as follows:
When described network element has back-to-back user agent B2BUA function, the service request after changing is produced new charging identifier, and in sending to the business request information of other network element, use described new charging identifier.Receive the final response of Client-initiated business request information when described network element after,, send the request of charging as the CDF network element, and in described request, carry described new charging identifier to charging entity.Described charging entity is chargeed to described service request according to described new charging identifier.
In addition, if described network element has back-to-back user agent B2BUA function, it can also produce the association identification of related described original charging identifier and new charging identifier to the service request after changing, and after the final response of the request of receiving, utilize described association identification and described new charging identifier to start the offline charging of the business that described user is carried out.Specific implementation process is as follows:
When described network element has back-to-back user agent B2BUA function, service request after changing is produced new charging identifier, and in sending to the business request information of other network element, use described new charging identifier, and produce that association identification is used for original charging identifier in the related described business request information that receives and the session request message sent in the charge information of new charging identifier correspondence.
Receive the final response of Client-initiated business request information when described network element after,, send the request of charging as the CDF network element, and in described request, carry charging identifier and described association identification to charging entity.
Described charging entity is chargeed to described service request according to the association identification of described charging identifier and related described charging identifier.
In addition, can pass to described AS network element by other network element if arrange association identification in advance, then described AS network element with back-to-back user agent B2BUA function is carried out following process:
When described network element had back-to-back user agent B2BUA function, the service request to after changing before continuing forwarding, produced new charging identifier, and uses described new charging identifier in sending to the business request information of other network element.
Judge whether to receive the association identification that other AS network element that described S-CSCF network element transmits sends to, if receive, then continue to use original charging identifier in the related described business request information that receives of described association identification and the business request information sent in the charge information of new charging identifier correspondence; If do not receive, then its produce that new, a unique association identification of the overall situation is used for original charging identifier in the related described business request information that receives and the business request information sent in the charge information of new charging identifier correspondence.
Receive the final response of Client-initiated business request information when described network element after,, send the request of charging as the CDF network element, and in described request, carry charging identifier and described association identification to charging entity.
Described charging entity is chargeed to described service request according to the association identification of described charging identifier and related described charging identifier.
The 3rd embodiment provided by the invention is the notion at session, its main thought is: after network entity AS receives business request information, before continuing to transmit the corresponding service request, after if the service request that its discovery is sent changes, then described network entity is handled described conversation request according to its function that has (have the Proxy function or have the B2BUA function).Specific implementation process is as follows:
When described network element has the Proxy function, then in the business request information of sending, continue to use original charging identifier.
When described network element had back-to-back user agent B2BUA function, if carry SDP information in the business request information that receives, and the session identification that comprises in the described SDP information then produced new charging identifier when changing; If do not carry SDP information in the business request information that receives, then judge whether to produce and use new charging identifier according to configuration information.Specific implementation process is as follows:
Step 2, when carrying SDP information in the business request information that described network element with back-to-back user agent B2BUA function receives, its processing procedure is as follows:
At first, described network element with back-to-back user agent B2BUA function is preserved the original charging identifier and the described SDP information of carrying in the business request information that receives.
Secondly, described network element with back-to-back user agent B2BUA function send the business request information relevant with described business request information to other network element before, check that whether the session identification that comprises in the SDP information in the related service request message to be sent equates with session identification in the business request information that receives:
If equate, then described network element continues to use original charging identifier;
If unequal, show that change has taken place user conversation.So described network element in the business request information of sending, does not re-use original charging identifier, but produce a new charging identifier, and described new charging identifier is encapsulated in the business request information to be sent, send to other network element then.
Then, receive the final response of Client-initiated business request information when described network element after, to charging entity,, and in described request, carry described new charging identifier as the request of send chargeing of CDF network element.Described charging entity is chargeed to described service request according to described new charging identifier.
In the step 2, described network element with back-to-back user agent B2BUA function can also produce the new charging identifier of related original charging identifier of association identification and generation, and after the final response that receives the Client-initiated business request information, utilize the offline charging of described association identification startup to the respective user business.Its processing procedure is as follows:
At first, described network element with back-to-back user agent B2BUA function is preserved the original charging identifier and the described SDP information of carrying in the business request information that receives.
Secondly, described network element with back-to-back user agent B2BUA function send the business request information relevant with described business request information to other network element before, check that whether the session identification that comprises in the SDP information in the related service request message to be sent equates with session identification in the business request information that receives:
If equate, then described network element continues to use original charging identifier;
If unequal, show that change has taken place user conversation.So described network element is in the business request information of sending, do not re-use original charging identifier, but produce a new charging identifier, produce new, an overall unique association identification SCID (Service Charging ID simultaneously,) the new charging identifier of related original charging identifier and generation, and preserve described new charging identifier, and described association identification.Then described new charging identifier is encapsulated in the business request information to be sent, also the association identification that produces can be encapsulated in the business request information to be sent, send to other network element.
Receive the final response of Client-initiated business request information when described network element after,, send the request of charging as the CDF network element, and in described request, carry described association identification to charging entity.
Described charging entity is chargeed to described service request according to described association identification.
If the network element that prior agreement has back-to-back user agent B2BUA function can receive the association identification that other AS network element of described S-CSCF network element forwarding passes to, then in the step 2, the processing procedure of described network element with back-to-back user agent B2BUA function is as follows:
At first, described network element with back-to-back user agent B2BUA function is preserved the original charging identifier and the described SDP information of carrying in the business request information that receives.
Secondly, described network element with back-to-back user agent B2BUA function send the business request information relevant with described business request information to other network element before, check that whether the session identification that comprises in the SDP information in the related service request message to be sent equates with session identification in the business request information that receives:
If equate, then described network element continues to use original charging identifier;
If unequal, show that change has taken place user conversation.So described network element in the business request information of sending, does not re-use original charging identifier, but produce a new charging identifier.Then judge in the business request information that receives whether comprise association identification,, then preserve described association identification if fruit comprises, and the new charging identifier that uses described association identification association to be produced; If do not comprise, then produce the new charging identifier of a related original charging identifier of association identification new, that the overall situation is unique and generation, and preserve described new charging identifier and described association identification.Then described new charging identifier is encapsulated in the business request information to be sent, also the association identification that produces can be encapsulated in the business request information to be sent, send to other network element.
Receive the final response of Client-initiated business request information when described network element after,, send the request of charging as the CDF network element, and in described request, carry described association identification to charging entity.Described charging entity is chargeed to described service request according to described association identification.
If have the SDP that does not carry in the NE Discovery message of back-to-back user agent B2BUA function, then described network element judges whether to produce new charging identifier according to configuration information.Specific implementation process is as follows:
At first, described network element is preserved the charging identifier that carries in the described business request information.
